Description

  The present invention relates to a broadcast recording apparatus that records content data representing the contents of a broadcast program on a recording medium such as an optical disk.

  Currently, recording devices (broadcast recording devices) that record programs broadcast by television broadcasting are widespread. The recording device includes a built-in storage device such as a hard disk, and stores content data representing contents such as video or audio of a program in the built-in storage device, and content on a portable recording medium such as a removable optical disk. Some of them record data.

In a recording apparatus provided with a built-in storage device, there is a problem that a program can be reproduced only by the recording apparatus that has performed recording. Further, if content data is continuously saved without being erased, there is a problem that the capacity of the built-in storage device is insufficient and the content data cannot be saved. These difficulties can be solved by dubbing content data from the built-in storage device to a portable recording medium.
However, there is a problem that a user who is unfamiliar with the operation of the recording apparatus has difficulty in dubbing operation and requires time and effort.

On the other hand, when a recording apparatus that can directly record content data on a portable recording medium is used, it is not necessary to perform the above dubbing. When a plurality of users use the same recording device at home, each user can hold his / her own recording medium, and each user can record a desired program on his / her own recording medium. In addition, when the user owns a plurality of recording devices, the recording can be performed on one recording medium using the plurality of recording devices.
However, when a recording reservation is made, the recording device stores the recording reservation information, so that even if another recording medium different from the recording medium that was scheduled to be used for recording is installed by mistake, There is a problem that content data is recorded on the recording medium. For example, to record the program a on the recording medium owned by Mr. A, it is necessary to make a recording reservation for the program a and attach the recording medium owned by Mr. A to the recording apparatus. Is attached to the recording apparatus, the program a is recorded on the recording medium of Mr. B.
In addition, when the recording medium is not loaded at the recording start time, there is a problem that recording becomes impossible. Of course, when a recording reservation is made, it is possible to restrict the recording / playback function so that the recording medium cannot be ejected, but other users cannot use the recording device and the convenience is impaired.
Further, there is disclosed a recording apparatus configured to allow a normal operation of the recording apparatus even in a reservation recording standby state and to issue a warning to a user when a recording medium different from the recording reservation setting is loaded. However (for example, Patent Documents 1 and 2), every time another user exchanges the recording medium, a warning is issued, which is very troublesome.

  FIG. 3 is an explanatory diagram conceptually showing the internal configuration of the storage unit 12. The storage unit 12 includes a management area for storing information for managing the storage contents of the storage unit 12, and a plurality of first areas, second areas,..., An nth area, and a spare area for storing content data. It is configured to include a storage area. Here, n is a positive integer. n is set to an appropriate value in advance, and when the recording apparatus 1 is shipped, the storage area of the storage unit 12 is divided in advance into a plurality of storage areas including a management area, first to nth areas, and a spare area. .

  Among the storage areas of the storage unit 12, the first to nth areas are storage areas for associating specific optical disks 6 individually and storing data corresponding to the associated optical disks 6. For example, a specific optical disk 61 is associated with the first area, and a specific optical disk 62 is associated with the second area. At the time of shipment of the recording apparatus 1, the optical disc 6 is not associated with any area. In order to use the recording apparatus 1, it is necessary to perform processing for registering the optical disk 6 owned by the user in association with any storage area. The spare area is a storage area for storing other data.

  As shown in FIG. 3, the management area of the storage unit 12 includes a management area management unit that stores information for managing the management area, a first area, a second area,..., An nth area, and a spare area. Are configured to include a first area management unit, a second area management unit,..., An nth area management unit and a spare area management unit. The management area is an allocation area indicating the number of entries indicating the number of divided storage areas of the storage unit 12 and the addresses of areas allocated to the first to nth area management units and the spare area management unit in the management area. Information is stored.

The first area management unit identifies an entry number indicating the number of the first storage area, an assignment flag indicating whether or not the optical disk 6 is actually associated with the first area, and the associated optical disk 6. Is stored. Further, the first area management unit includes allocation area information indicating an address of an area allocated to the first area in the storage area of the storage unit 12, media key information that is information used for copy guard of the optical disc 6, In addition, map information indicating the distribution state of data related to the first region is stored. The media ID and the media key information are information recorded in advance on the optical disc 6 and are information specific to each optical disc 6. That is, the media ID and media key information correspond to the media information in the present invention. At the time of shipment of the recording apparatus 1, since the optical disc 61 is not yet associated with the first area, the allocation flag indicates that the optical disc 6 is not associated, and the media ID unique to the specific optical disc 61 is shown. And media key information is not yet stored. The map information indicates to which address of the first area and the optical disc 61 the data stored in the first area and the data recorded on the optical disc 61 associated with the first area are distributed. Similar information is stored in each of the second to n-th area management units.
Note that the recording apparatus 1 does not divide the storage area of the storage unit 12 in advance, but determines n by the user specifying the value of n, and stores the storage unit 12 according to the value of n. The form which performs the process which divides | segments an area | region may be sufficient.
Next, processing executed by the recording apparatus 1 having the above configuration will be described.

<Storage area division processing>
FIG. 4 is a flowchart illustrating a procedure of processing for dividing the storage area of the storage unit 12. The recording / playback control unit 24 causes the video display device 4 to display an acceptance screen for accepting designation of the number of optical disks 6 that can be registered in the recording device 1, and receives a signal from the remote controller 5 on which the user has performed a predetermined operation. The remote controller receiving unit 33 receives the designation of the number of optical disks 6 that can be registered (step S11). Then, the recording / playback control unit 24 sets the number of entries by causing the management area management unit of the storage unit 12 to store the value of the designated number as the number of entries n (step S12). Next, the recording / playback control unit 24 secures the first to nth region management units and the spare region management unit in the management region of the storage unit 12, and manages the allocation area information indicating the addresses of the allocated areas. By storing in the area manager, the first area manager, the second area manager,..., The nth area manager and the spare area manager are set (step S13). Next, the recording / playback control unit 24 divides the storage area other than the management area of the storage unit 12 into (n + 1), and an allocation area indicating addresses of areas allocated to the first to nth areas and the spare area, respectively. The information is stored in each of the first to nth area management units and the spare area management unit, thereby setting the first to nth areas and the spare area (step S14). The recording device 1 ends the process of dividing the storage area of the storage unit 12 as described above.

<Registration process>
FIG. 5 is a flowchart showing a procedure of processing performed by the recording apparatus 1 after the optical disc 6 is loaded in the optical disc drive 11. When the optical disk 6 is loaded into the optical disk drive 11 by a user operation, the drive control unit 13 causes the optical disk drive 11 to read information recorded at a predetermined position in the optical disk 6, thereby The media ID is read, and the read media ID is output from the interface unit 14 to the back-end unit 20. The recording / playback control unit 24 acquires the media ID via the interface unit 26 and determines whether the acquired media ID is stored in any of the first to nth area management units of the storage unit 12. Then, it is determined whether or not the mounted optical disk 6 is an already registered optical disk 6 (step S31). When the media ID is not stored in the storage unit 12 and it is determined that the optical disc 6 has not been registered (step S31: NO), the recording / playback control unit 24 adds the data read from the optical disc 6 by the optical disc drive 11 to the data read out. Based on this, it is determined whether or not the optical disk 6 is a formatted optical disk 6 (step S32). In step S32, the determination is made based on, for example, a volume descriptor. When it is determined that the optical disk 6 is the formatted optical disk 6 (step S32: YES), the recording / playback control unit 24 uses the optical disk drive 11 to read the optical disk 6 from the optical disk 6, and the optical disk 6 is a read-only optical disk 6. It is determined whether or not (step S33).

  When it is determined that the optical disc 6 is not for reproduction only (step S33: NO), the recording / playback control unit 24 determines whether or not a format instruction for the optical disc 6 has been received (step S34). For example, the recording / playback control unit 24 transmits a reception screen video signal for receiving a format instruction of the optical disc 6 from the signal output unit 34 to the video display device 4 via the decoder 28 and the image processing unit 29. Then, the video display device 4 displays a reception screen for receiving a format instruction. The user who confirms the reception screen inputs a format instruction by operating the remote controller 5 when formatting. When the remote control receiving unit 33 receives a predetermined signal transmitted by the remote controller 5 that has received a predetermined operation from the user, and determines that the format instruction for the optical disc 6 has been received (step S34: YES), or step S32 When it is determined that the optical disc 6 has not been formatted (step S32: NO), the recording / playback control unit 24 causes the drive control unit 13 and the optical disc drive 11 to format the optical disc 6 (step S35). When it is determined that the format instruction for the optical disk 6 is not received (step S34: NO), the recording / playback control unit 24 determines whether a registration instruction for the optical disk 6 is received (step S36). For example, the recording / playback control unit 24 causes the video display device 4 to display a reception screen for receiving a registration instruction, and the remote control reception unit 33 receives an instruction as to whether or not to register the optical disc 6. In addition, you may perform the process which displays the reception screen which united the reception screen for receiving a format instruction | indication, and the reception screen for receiving a registration instruction | indication on the video display apparatus 4. FIG.

  When the process of step S35 is completed, or when it is determined in step S36 that a registration instruction for the optical disc 6 has been received (step S36: YES), the recording / playback control unit 24 stores information stored in the management area of the storage unit 12 Based on the above, it is determined whether there is a storage area that is not associated with the optical disc 6 in the first to nth areas of the storage unit 12 (step S37). When it is determined that there is no storage area not associated with the optical disk 6 (step S37: NO), the recording / playback control unit 24 selects any one of the optical disks 6 registered in association with each storage area. It is determined whether or not an instruction to cancel registration of the optical disc 6 has been received (step S38). For example, the recording / playback control unit 24 displays on the video display device 4 an acceptance screen for accepting an instruction to cancel registration of the optical disc 6 that has already been registered after notifying that the new registration of the optical disc 6 cannot be performed. The remote control receiving unit 33 receives an instruction as to whether or not to cancel the registration. In addition, you may perform the process which also receives the instruction | indication of which optical disk 6 registration is canceled. When it is determined that the registration cancellation instruction has been received (step S38: YES), the recording / playback control unit 24 stores the drive control unit 13 in the medium unique to the one optical disc 6 stored in the management area of the storage unit 12. By deleting the information, a process for canceling the registration of one optical disk 6 is performed (step S39). For example, when the registration of the optical disc 61 associated with the first area of the storage unit 12 is canceled, the recording / playback control unit 24 uses the media ID and media stored in the first area management unit of the storage unit 12. Performs processing to delete key information. At this time, the allocation flag stored in the first area management unit is rewritten to a flag indicating that the optical disc 6 is not associated.

  When it is determined in step S37 that there is a storage area that is not associated with the optical disk 6 (step S37: YES), or when step S39 is completed, the recording / playback control unit 24 detects the optical disk loaded in the optical disk drive 11. 6 is stored in the management area of the storage unit 12 in association with a storage area that is not associated with the optical disk 6, thereby registering the optical disk 6 in association with the storage area (step S40). ). For example, when the optical disc 61 is associated with the first area of the storage unit 12, the recording / playback control unit 24 stores the media ID and media key information read from the optical disc 61 loaded in the optical disc drive 11 in the first part of the storage unit 12. Processing to be stored in the area management unit is performed. Further, the allocation flag stored in the first area management unit is rewritten to a flag indicating that the optical disk 6 is associated. When it is determined in step S31 that the media ID is stored in the storage unit 12 and the optical disc 6 has been registered (step S31: YES), or when the process of step S40 is completed, the recording / playback control unit 24 In order to execute processing such as recording or reproduction, access to the optical disk 6 loaded in the optical disk drive 11 is started (step S41).

  If it is determined in step S33 that the optical disk 6 is for reproduction only (step S33: YES), if it is determined in step S16 that no registration instruction for the optical disk 6 has been received (step S36: NO), or registration is canceled in step S38. When the recording / playback control unit 24 determines that the instruction is not received (step S38: NO), the recording / playback control unit 24 starts accessing the optical disk 6 mounted in the optical disk drive 11 as an unregistered optical disk 6 ( Step S42). The recording device 1 ends the process when the optical disc 6 is loaded.

<Recording reservation processing>
The recording device 1 performs a recording reservation process in a state where the registered optical disc 6 is mounted on the optical disc drive 11.
FIG. 6 is a flowchart showing a procedure of recording reservation processing performed by the recording apparatus 1. The recording / playback control unit 24 displays an acceptance screen for accepting designation of a program to be recorded on the video display device 4, and the remote control receiving unit 33 receives a signal from the remote controller 5 on which a user has performed a predetermined operation. Thus, designation of a program to be recorded is accepted (step S51). For example, the video display device 4 displays an electronic program guide, and the user operates the remote controller 5 while confirming the electronic program guide, whereby the program is designated on the electronic program. Next, the recording / playback control unit 24 generates reservation information for designating a program reserved for recording in accordance with the designation of the received program, and associates the reservation information with the media ID of the optical disc 6 loaded in the optical disc drive 11. Is stored in the storage memory 27 (step S52). Next, the recording / playback control unit 24 causes the drive control unit 13 and the optical disc drive 11 to record reservation information on the optical disc 6 loaded in the optical disc drive 11 (step S53). The recording apparatus 1 ends the recording reservation process.

  FIG. 7 is a conceptual diagram showing an example of the contents of reservation information stored in the storage memory 27. The media ID and the reservation information are stored in association with each other. The reservation information includes information indicating the broadcast date and time of the channel and program, and the program to be recorded is designated by these information. That is, the reservation information is information for designating a program in which content data is to be recorded, and corresponds to the program designation information in the present invention. The reservation information may be stored in association with the entry number of the storage area of the storage unit 12 corresponding to the optical disc 6 instead of the media ID. In this way, the storage memory 27 stores the reservation information in association with the registered optical disk 6.

<Warning process>
8 and 9 are flowcharts showing the procedure of warning processing performed by the recording apparatus 1. The following processing is periodically executed. The recording / playback control unit 24 determines whether or not the storage memory 27 stores reservation information (step S71). When it is determined that the storage memory 27 stores reservation information (step S71: YES), the recording / playback control unit 24 stores a storage area corresponding to the media ID associated with the reservation information (hereinafter referred to as a corresponding area). ) Determines whether there is sufficient free space for recording the content data of the program (step S72). Specifically, the recording / playback control unit 24 estimates the storage capacity necessary for recording the content data based on the reservation information stored in the storage memory 27. Then, the recording / playback control unit 24 specifies the free space in the corresponding area based on the information stored in the management area of the storage unit 12, and compares the specified free capacity with the estimated storage capacity. By doing so, it is determined whether or not there is sufficient free space in the corresponding area.

  If it is determined that there is not enough free space in the corresponding area (step S72: NO), the recording / playback control unit 24 determines whether or not the optical disk 6 is loaded in the optical disk drive 11 (step S73). When it is determined that the optical disk 6 is not loaded (step S73: NO), the recording / playback control unit 24, based on the reservation information stored in the storage memory 27 and the time counted by the clock unit, It is determined whether it is a predetermined time before the reserved recording start time, for example, 10 minutes before (step S74). When it is determined that it is a predetermined time before the scheduled recording start time (step S74: YES), the recording / playback control unit 24 issues a warning that the optical disk 6 corresponding to the media ID associated with the scheduled information should be mounted. A video signal for performing the warning is displayed on the video display device 4 by transmitting the video signal to be transmitted from the signal output unit 34 to the video display device 4 via the decoder 28 and the image processing unit 29 (step S81). ) Finish the process. Hereinafter, the video for performing the warning is referred to as a mounting warning video.

If it is determined that it is not a predetermined time before the scheduled recording start time (step S74: NO), the recording / playback control unit 24 determines whether or not the main power supply has been turned off based on the signal received by the remote control receiving unit 33. Is determined (step S75). When it is determined that there has been a power-off operation (step S75: YES), the recording / playback control unit 24 issues a mounting warning for warning that the optical disk 6 corresponding to the media ID associated with the reservation information should be mounted. The video is displayed on the video display device 4 (step S81).
If it is determined in step S71 that the storage memory 27 does not store reservation information (step S71: NO), if it is determined in step S72 that there is sufficient free space in the corresponding area (step S72: YES), or If it is determined in step S75 that there is no power-off operation (step S75: NO), the recording / playback control unit 24 ends the process.

  If it is determined in step S73 that the optical disc 6 is loaded (step S73: YES), the recording / playback control unit 24 is based on the signal received by the remote control receiving unit 33 and whether or not the optical disc 6 has been ejected. Is determined (step S76). If it is determined that there has been an eject operation (step S76: YES), the recording / playback control unit 24 causes the video display device 4 to display a mounting warning video (step S81).

  When it is determined that there is no ejection operation (step S76: NO), the recording / playback control unit 24 determines whether or not the mounted optical disk 6 is the optical disk 6 associated with the reservation information (step S77). . Specifically, the recording / playback control unit 24 causes the drive control unit 13 and the optical disc drive 11 to read the media ID from the mounted optical disc 6 and associates the read media ID with the reservation information. Compare the media ID. Then, when the media IDs match, the recording / playback control unit 24 determines that the optical disc 6 is associated with the reservation information.

  When it is determined that the optical disk 6 is associated with the reservation information (step S77: YES), the recording / playback control unit 24 ends the process. If it is determined that the reservation information is not the associated optical disk 6 (step S77: NO), the recording / playback control unit 24 determines whether or not the moving image state of the recording device 1 has transitioned to the stopped state (step S78). . Specifically, the recording / playback control unit 24 determines whether or not an instruction to stop the recording apparatus 1 has been given based on the signal received by the remote control receiving unit 33. When it determines with having changed to the stop state (step S78: YES), a control part displays the attachment warning image | video on the video display apparatus 4 (step S81).

  When it is determined that the stop of the recording device 1 is not instructed (step S78: NO), the recording / playback control unit 24 determines the reservation information stored in the storage memory 27 and the time counted by the clock unit. Based on this, it is determined whether or not it is a predetermined time before the reserved recording start time (step S79). If it is determined that it is a predetermined time before the scheduled recording start time (step S79: YES), the recording / playback control unit 24 displays the attachment warning video on the video display device 4 (step S81), and ends the process.

  When it is determined that it is not a predetermined time before the scheduled recording start time (step S79: NO), the recording / playback control unit 24 determines whether or not the main power supply has been turned off based on the signal received by the remote control receiving unit 33. Is determined (step S80). If it is determined that there has been no power-off operation (step S80: NO), the recording / playback control unit ends the process. If it is determined that the power-off operation has been performed (step S80: YES), the recording / playback control unit 24 issues a mounting warning for warning that the optical disk 6 corresponding to the media ID associated with the reservation information should be mounted. The video is displayed on the video display device 4 (step S81).

  10 and 11 are flowcharts showing the procedure of the recording process performed by the recording apparatus 1. The recording / playback control unit 24 measures the date and time using the clock unit, and determines at any time whether or not the broadcast date and time of the program indicated by the information included in the reservation information stored in the storage memory 27 has been reached (step). S91). When it is determined that it is not yet the broadcast date / time of the program (step S91: NO), the recording / playback control unit 24 continues to measure the date / time. When the broadcast date and time of the program indicated by the information included in the reservation information is reached (step S91: YES), the recording / playback control unit 24 determines whether or not the optical disc 6 is loaded in the optical disc drive 11 (step S92). ). When it is determined that the optical disk 6 is loaded in the optical disk drive 11 (step S92: YES), the recording / playback control unit 24 includes reservation information including information indicating the broadcast date and time of the optical disk 6 loaded in the optical disk drive 11. It is determined whether or not the optical disc 6 is associated with (step S93). In step S93, the recording / playback control unit 24 reads the media ID from the optical disc 6, and the media ID stored in the storage memory 27 in association with the reservation information matches the media ID output to the read optical disc drive 11. The determination is made according to whether or not.

  If it is determined in step S93 that the media IDs match and the optical disk 6 is the optical disk 6 associated with the reservation information (step S93: YES), the recording / playback control unit 24, as shown in FIG. Then, the content data representing the contents of the program for which broadcasting has been started is recorded on the optical disc 6 by the optical disc drive 11 (step S94). Details will be described later with reference to FIG. In step S94, the digital tuner 21 converts the broadcast signal of the channel indicated by the reservation information into stream data, the stream processing unit 23 performs data processing on the stream data, and the recording / playback control unit 24 converts the stream data into the interface unit 26. To the hybrid drive unit 10. Stream data is content data that can reproduce a program by decoding and represents the contents of the program. In step S94, the recording / playback control unit 24 causes the drive control unit 13 to record content data on the optical disc 6 by the optical disc drive 11. For example, when the reservation information specifying the program that has reached the broadcast date and time is associated with the optical disc 61 and the optical disc 61 is loaded in the optical disc drive 11, the content data is recorded on the optical disc 61. The recording / playback control unit 24 records the content data on the optical disc 6 and stores the content data in a storage area corresponding to the optical disc 6 associated with the reservation information in the storage area of the storage unit 12. May be performed.

  When the broadcast of the program ends and the recording of the content data ends, the recording / playback control unit 24 records title information indicating the title of the program represented by the content data recorded on the optical disc 6 on the optical disc 6 (step S95). . As the title of the program, a title determined based on information included in the broadcast signal received by the digital tuner 21 such as a title displayed in the electronic program guide may be used, and the user operates the remote controller 5. The title set by may be used.

  When it is determined in step S92 that the optical disc 6 is not loaded in the optical disc drive 11 (step S92: NO), or in step S93, the media IDs do not match and the optical disc 6 is associated with the reservation information. If it is determined that there is not (step S93: NO), the recording / playback control unit 24 determines whether or not there is a free capacity for storing the content data of the program in the corresponding area (step S96). That is, it is determined whether or not there is sufficient free space in the storage area corresponding to the media ID associated with the reservation information to store the content data of the program reserved for recording.

  If it is determined that there is free space in the corresponding area (step S96: YES), the recording / playback control unit 24 stores content data representing the content of the program for which broadcasting has started, as shown in FIG. Are stored in a corresponding area corresponding to the media ID associated with the reservation information (step S97). For example, reservation information for designating a program whose broadcast date and time is associated with the optical disc 61 and the optical disc 6 is not installed in the optical disc drive 11 or an optical disc 6 other than the optical disc 61 is installed in the optical disc drive 11. If it is, the content data is stored in the first area of the storage unit 12. Details of FIG. 13 will be described later.

  If it is determined that there is no free space for storing the content data in the corresponding area (step S96: NO), the recording / playback control unit 24 has enough free space to store the content data of the program in the spare area. It is determined whether or not there is (step S98). If it is determined that there is sufficient free space in the spare area (step S98: YES), the recording / playback control unit 24 stores content data representing the content of the program for which broadcasting has started, as shown in FIG. The data is stored in the spare area of the unit 12 (step S99). Details of FIG. 14 will be described later.

  When it is determined that there is no free space in the spare area (step S98: NO), the recording / playback control unit 24 is sufficient to store the program content data in a storage area other than the corresponding area and the spare area. It is determined whether there is free space (step S100). If it is determined that there is not enough free space in the other storage area (step S100: NO), the recording / playback control unit 24 ends the process. When it is determined that there is sufficient free space in another storage area (step S100: YES), the recording / playback control unit 24 stores content data representing the content of the program for which broadcasting has started, as shown in FIG. Then, it is stored in the other storage area (step S101). Details of FIG. 15 will be described later.

  When the processing of step S95, step S97, step S99, or step S101 is completed, the recording / playback control unit 24 stores title information equivalent to the title information recorded on the optical disc 6 in the storage memory 27 ( Step S102). The recording / playback control unit 24 may perform a process of storing the title information in a storage area corresponding to the optical disc 6 associated with the reservation information in the storage area of the storage unit 12.

  Next, the recording / playback control unit 24 updates the map information indicating the distribution state of the content data recorded on the optical disc 6 or the content data stored in the storage unit 12 to reflect the processing up to step S102 (step S103). ). Then, the recording / playback control unit 24 performs a process of deleting the reservation information of the program that has been recorded from the optical disc 6 and the storage memory 27 (step S104), and ends the recording process.

12 to 15 are conceptual diagrams showing states of the optical disc 6 on which content data is recorded or the storage unit 12 in which content data is stored. FIG. 12A shows a state in which the content data of program 1 is recorded on the optical disc 61 in step S94. Further, the recorded contents of the optical disc 61, the recorded contents of the first area, and the data to be stored in the first area. Shows a recording image of a virtual disk (virtual disk) that records content data included in at least one of the spare area and the n-th area temporarily stored therein. The content data of the program 1 is stored on the optical disc 61, and accordingly, the content data is also recorded on the virtual disc. FIG. 12B shows an example of the contents of the map information stored in the first area management unit of the storage unit 12. In association with the data name of the content data, the data distribution in the virtual disk is recorded by the head address and the data size. Further, information indicating the synchronization state of the content data between the first area and the disc 61 is recorded. Since the content data has been recorded on the optical disc 61 from the beginning, no information is stored in the item of the synchronization state. Furthermore, when the information to be stored in the first area is stored in another storage area or the spare area, temporary storage information indicating the storage area that should have been stored originally is stored in association with the data name. . In FIG. 12, since the content data of the program 1 is recorded on the optical disc 61 that should be stored, no information is stored in the item of temporary storage information.
In this embodiment, the memory address and the data size are represented by decimal numbers. FIG. 12C shows an example of the content of title information. In association with the title of the program represented by the content data, information indicating the length of time that the program lasts, the image quality, the number of possible dubs, and the synchronization state is recorded. Note that the data name and title name of the content data may be the same as shown in FIG. 12, but may be different from each other.

  FIG. 13 shows a state in which the content data of program 1 is recorded in the first area of the storage unit 12 in step S97. As shown in FIG. 13A, the content data of the program 1 is stored in the first area, and the content data is recorded on the virtual disk accordingly. As shown in FIG. 13B, in the map information, the distribution of data in the virtual disk and the first area is recorded by the head address and the data size in association with the data name of the content data. Further, information indicating the synchronization state of the content data between the first area and the disc 61 is recorded. Since the content data is not recorded on the optical disc 61, the synchronization state is not synchronized. In FIG. 13, since the content data of program 1 is recorded in the first area that should be stored, no information is stored in the item of temporary storage information. Further, as shown in FIG. 13 (c), in the title information, the content data recorded in the first area is recorded 10 times as the possible number of dubbing.

  FIG. 14 shows a state in which the content data of program 1 is recorded in the spare area of the storage unit 12 in step S99. As shown in FIG. 14A, the content data of the program x has already been recorded in the first area, and no free space for storing the content data of the first program remains in the first area. For this reason, the content data of the program 1 is stored in the spare area, and accordingly, the content data is also recorded on the virtual disk. As shown in FIG. 14B, in the map information, the distribution of data in the virtual disk and the spare area is recorded according to the head address and the size of the data in association with the data name of the content data. Furthermore, information indicating the synchronization state of the content data in the spare area and the disc 61 is recorded. Since the content data is not recorded on the optical disc 61, the synchronization state is not synchronized. In FIG. 14, since the content data of the program 1 is not recorded in the first area that should be stored, information indicating the first area where the content data of the first program should be stored is stored. ing. Further, as shown in FIG. 14C, in the title information, 10 times are recorded as the number of possible dubbing for the content data recorded in the spare area.

  FIG. 15 shows a state in which the content data of program 1 is recorded in the nth area of the storage unit 12 in step S101. As shown in FIG. 15 (a), the content data of the program x and the program y are already recorded in the first area and the spare area, respectively, and there is a free space for storing the content data of the first program. It remains in neither the one area nor the spare area. For this reason, the content data of the program 1 is stored in the nth area, and the content data is recorded on the virtual disk accordingly. As shown in FIG. 15B, in the map information, the distribution of data in the virtual disk and the nth area is recorded by the head address and the data size in association with the data name of the content data. Furthermore, information indicating the synchronization state of the content data in the nth area and the disc 61 is recorded. Since the content data is not recorded on the optical disc 61, the synchronization state is not synchronized. In FIG. 15, since the content data of program 1 is not recorded in the first area that should be stored, information indicating the first area where the content data of the first program should be stored is stored. ing. Further, as shown in FIG. 15C, in the title information, the content data recorded in the nth area is recorded 10 times as the possible number of dubbing.

<Synchronization / transfer processing>
After starting to access the registered optical disc 6 in step S31, the recording device 1 performs processing for synchronizing the recorded content of the optical disc 6 with the stored content in the corresponding storage area of the storage unit 12.
FIGS. 16 and 17 are flowcharts showing the procedure of the synchronization process performed by the recording apparatus 1. After starting access to the optical disc 6 in step S31, the recording / playback control unit 24 compares the recorded content of the optical disc 6 with the stored content in the storage area corresponding to the optical disc 6 in the storage area of the storage unit 12. Then, it is determined whether or not content data not recorded on the optical disc 6 is stored in the corresponding storage area (step S111). In step S111, for example, it is determined whether content data not recorded on the optical disc 61 is stored in the first storage area of the storage unit 12, or whether it is stored in the spare area or another storage area. If unrecorded content data is stored (step S111: YES), the recording / playback control unit 24 determines whether there is reservation information recorded on the optical disc 6 (step S112). When it is determined that there is reservation information recorded on the optical disc 6 (step S112: YES), the recording / playback control unit 24 determines whether or not there is free space in the corresponding area (step S113).

  When it is determined that there is no free space in the corresponding area (step S113: NO), the recording / playback control unit 24 deletes the content data stored in the storage unit 12 after completing the synchronization of the unrecorded content data. The power display is displayed on the video display device 4 (step S114). Next, the recording / playback control unit 24 determines whether or not to delete the data in the corresponding area based on the signal received by the remote control receiving unit 33 (step S115).

  If it is determined in step S112 that no reservation information is recorded on the optical disc 6 (step S112: NO), if it is determined in step S113 that there is a free space in the corresponding area (step S113: YES), or it is handled in step S115. When it is determined not to delete the data in the area (step S115: NO), the recording / playback control unit 24 copies unrecorded content data from the storage unit 12 to the optical disc 6 (step S117). In step S 117, the recording / playback control unit 24 causes the drive control unit 13 to read unrecorded content data from the storage unit 12 and record the read content data on the optical disc 6 using the optical disc drive 11.

  If it is determined in step S115 that content data in the corresponding area is to be deleted (step S115: YES), the recording / playback control unit 24 transfers unrecorded content data from the storage unit 12 to the optical disc 6 (step S116). That is, after copying unrecorded content data from the storage unit 12 to the optical disc 6, the content data stored in the storage unit 12 is deleted.

  When the process of step S116 or step S117 is completed, the recording / playback control unit 24 next updates the title information stored in the storage memory 27 so as to reflect the state in which the content data is recorded on the optical disc 6. (Step S118), the map information stored in the management area of the storage unit 12 is updated (Step S119). In step S119, for example, the map information stored in the first area management unit of the storage unit 12 is updated so as to reflect the state in which the optical disc 61 has recorded the content data.

  Next, the recording / playback control unit 24 determines whether or not the reservation information related to the content data recorded on the optical disc 6, that is, the reservation information generated for recording the program represented by the content data is recorded on the optical disc 6. Is determined (step S120). When the reservation information related to the content data recorded on the optical disc 6 is recorded on the optical disc 6 (step S120: YES), the recording / playback control unit 24 corresponds to the drive control unit 13 from the optical disc 6 with the optical disc drive 11. The reservation information is deleted (step S121).

  When unrecorded content data is not stored on the optical disc 6 in step S121 (step S111: NO), reservation information related to the content data recorded on the optical disc 6 in step S120 is not recorded on the optical disc 6 (step S120). : NO) or after step S121 is completed, the recording / playback control unit 24 determines whether reservation information that is not yet stored in the storage memory 27 is recorded on the optical disc 6 (step S122). When reservation information that is not stored in the storage memory 27 is recorded on the optical disc 6 (step S122: YES), the recording / playback control unit 24 copies the reservation information that is not stored from the optical disc 6 to the storage memory 27. (Step S123). In step S123, the recording / playback control unit 24 causes the drive control unit 13 to read reservation information that is not yet stored from the optical disc 6 by the optical disc drive 11, and inputs the reservation information to the back end unit 20 via the interface unit 14. The inputted reservation information is stored in the storage memory 27. The reservation information recorded on the optical disc 6 and the reservation information stored in the storage memory 27 coincide with each other by the processing of step S121 and step S123.

  When unstored reservation information is not recorded on the optical disc 6 in step S122 (step S122: NO), or when the processing of step S123 is completed, the recording / playback control unit 24 determines that the free space of the optical disc 6 is a predetermined capacity. It is determined whether it is less than (step S124). When it is determined that the free capacity of the optical disk 6 is less than the predetermined capacity (step S124: YES), the recording / playback control unit 24 causes the video display device 4 to display a video to be replaced with a new optical disk 6 ( Step S125).

  When the process of step S125 is completed, or when it is determined in step S124 that the free space of the optical disc 6 is equal to or larger than the predetermined amount (step S124: NO), the recording / playback control unit 24 stores information stored in the management area. Based on the above, it is determined whether there is another unsynchronized optical disk 6 (step S126). When it is determined that there is no unsynchronized optical disk 6 (step S126: NO), the control unit ends the process. When it is determined that there is an unsynchronized optical disk 6 (step S126: YES), the recording / playback control unit 24 causes the video display device 4 to display a video indicating that another optical disk 6 should be synchronized (step S126). S127), the process ends.

  FIG. 18 is a conceptual diagram showing a result of synchronizing the recorded content of the optical disc 6 with the stored content of the storage unit 12. FIG. 18 shows a synchronization result when the optical disc 61 on which no content data is recorded is loaded in the optical disc drive 11 in the state shown in FIG. As shown in FIG. 18A, the same content data as the content data stored in the first area is recorded on the optical disc 61. The data distribution of the virtual disk is a data distribution that reflects the data distribution on the optical disk 6. Further, as shown in FIG. 18B, in the map information, the content data of the program 1 is stored in both the virtual disk and the first area, and the recorded contents of the optical disc 61 and the storage of the first area regarding the content data of the program 1 are stored. It is recorded that the contents are synchronized. As shown in FIG. 18B, in the map information, the location of the content data representing the same program on the virtual disk, that is, the location on the optical disc 6 and the location on the storage unit 12 are associated with each other. Therefore, by referring to the map information, it is possible to access content data representing the same program in both the optical disc 6 and the storage unit 12. As shown in FIG. 18C, the title information also records that the content data of the program 1 is synchronized between the optical disc 61 and the first area.

  Further, as shown in FIGS. 14 and 15, when content data to be stored in the first area is temporarily stored in the spare area or the nth area, the contents stored in the spare area or the nth area The data is transferred to the optical disc 6 and the first area, and the content data is deleted from the spare area and the nth area. By transferring the content data in this way, the storage state of the content becomes the state shown in FIG. When the transfer of the content data is finished, the temporary storage information corresponding to the spare area and the nth area is deleted, and the map information is also updated.

  FIG. 19 is a conceptual diagram illustrating a result of deleting content data from the storage unit 12 by synchronizing the recorded content of the optical disc 6 with the storage content of the storage unit 12. FIG. 19 shows the results of synchronization and transfer when the optical disc 61 on which no content data is recorded is loaded in the optical disc drive 11 in the state shown in FIGS. As shown in FIG. 19A, on the optical disc 61, the content data of the program x stored in the first area and the content data of the program 1 stored in the spare area or the nth area are stored on the optical disc 6. Has been transferred to. The data distribution of the virtual disk is a data distribution that reflects the data distribution on the optical disk 6. Further, as shown in FIG. 19B, the map information reflects the state where the first area is empty, and is in an empty state.

<Reproduction processing>
The recording device 1 can reproduce the program based on the content data recorded on the optical disc 6 after completing the synchronization process.
FIG. 20 is a flowchart showing a procedure of program playback processing performed by the recording apparatus 1. When the user performs a predetermined operation on the remote controller 5, the remote control receiver 33 receives an instruction to start the program playback process, and the recording / playback controller 24 displays the program represented by the content data recorded on the optical disc 6. A program selection screen for selecting a program to be reproduced is displayed on the video display device 4 (step S131). In step S131, the recording / playback control unit 24 extracts the title of the program represented by the content data recorded on the optical disc 6 loaded in the optical disc drive 11, from the title information stored in the storage memory 27, A video signal necessary to display the program selection screen including the extracted title is output from the signal output unit 34 to the video display device 4. The video display device 4 displays a program selection screen based on the video signal from the recording device 1. On the program selection screen, a list of programs represented by the content data recorded on the optical disc 6, that is, a list of reproducible programs is displayed. Note that the recording / playback control unit 24 may execute the process of step S131 immediately after the synchronization process illustrated in the flowchart of FIG. 16 ends.

  When the user who has confirmed the program selection screen operates the remote controller 5 and receives a signal from the remote controller 5 at the remote controller receiver 33, the recording / playback controller 24 selects the program to be played back from the user. Accept. After step S131, the recording / playback control unit 24 waits for reception of a program playback instruction by receiving selection of a program to be played back (step S132). If there is no reception of a program playback instruction (step S132: NO), the recording / playback control unit 24 continues to wait for reception of a program playback instruction. When a program playback instruction is received (step S132: YES), the recording / playback control unit 24 stores content data representing a program to be played back in a storage area associated with the optical disk 6 of the storage unit 12. It is determined whether or not there is (step S133). For example, when the program 1 represented by the content data recorded on the optical disc 61 is to be reproduced, it is determined whether or not the content data of the program 1 is stored in the first area. In step S131, the recording / playback control unit 24 refers to the title information, and the content data is stored in the storage unit 12 when the synchronization state information associated with the title name of the program to be played back indicates synchronization. It may be determined that the content data is not stored when synchronization is not indicated. Note that the recording / playback control unit 24 may perform a process of determining whether content data is stored in the storage unit 12 by referring to the map information stored in the management area of the storage unit 12. .

  When content data representing a program to be reproduced is stored in the storage area associated with the optical disc 6 of the storage unit 12 (step S133: YES), the recording / playback control unit 24 is stored in the storage unit 12. A process for reproducing the program is performed based on the content data (step S134). In step S134, the recording / playback control unit 24 identifies the address where the content data is stored by referring to the map information stored in the management area of the storage unit 12, and plays it back to the drive control unit 13. The content data representing the program to be played is read from the storage unit 12 and the content data is input to the backend unit 20 via the interface unit 14. Further, the recording / playback control unit 24 causes the decoder 28 to decode the input content data into a video signal and an audio signal, causes the image processing unit 29 to perform image processing, and outputs the video from the signal output unit 34 to the video display device 4. A signal and an audio signal are output. The video display device 4 reproduces a program by displaying video and outputting audio based on the video signal and audio signal from the recording device 1.

  When content data representing a program to be played back is not stored in the storage area associated with the optical disc 6 in the storage unit 12 (step S133: NO), the recording / playback control unit 24 is attached to the optical disc drive 11. The program is played back based on the content data recorded on the optical disc 6 (step S135). In step S135, the recording / playback control unit 24 causes the drive control unit 13 to read content data representing a program to be played back from the optical disc 6 by the optical disc drive 11, and sends the content data to the back end unit 20 via the interface unit 14. Let the data be entered. Further, the recording / playback control unit 24 causes the decoder 28 to decode the content data, causes the image processing unit 29 to perform image processing, and causes the signal output unit 34 to output a video signal and an audio signal. The video display device 4 reproduces a program based on the video signal and the audio signal from the recording device 1.

  As described in detail above, the recording apparatus 1 which is a broadcast recording apparatus of the present invention is provided with a storage unit 12 having a plurality of storage areas separately from the optical disk drive 11, and is associated with a specific storage area of the optical disk 6. By storing the media ID, a specific optical disk 6 is registered in association with a specific storage area. The recording device 1 stores the reservation information for recording in association with the optical disc 6, and records the content data on the optical disc 6 when the optical disc 6 associated with the reservation information is loaded when the program to be recorded is broadcast, When the optical disc 6 associated with the reservation information is not loaded, the content data is stored in the storage area corresponding to the optical disc 6. In addition, the recording apparatus 1 collectively manages information indicating content data to be recorded on the optical disc 6 and content data to be stored in a storage area corresponding to the optical disc 6, and when the optical disc 6 is loaded, the optical disc 6. Is recorded on the optical disc 6 and when the program is reproduced, the program is reproduced based on the content data stored in the storage area. As described above, the recording device 1 uses each storage area of the storage unit 12 as a cache area that assists reading and writing of content data with respect to the optical disc 6.

The content data is recorded on the optical disc 6 when the optical disc 6 is loaded later. Therefore, even if the user forgets to attach the optical disc 6 to the recording apparatus 1 even when the program starts broadcasting, the program can be recorded reliably. Further, even when the user mistakenly attaches the optical disc 6 different from the specific optical disc 6 on which the content data is to be recorded, to the recording device 1, the content data is recorded on the optical disc 6 that is erroneously attached. The content data is recorded on the correct optical disk 6 at a later date. As described above, the present invention enables reliable recording of content data at a low cost without requiring a large-capacity hard disk and a plurality of tuners.

  Further, by storing the content data in the storage unit 12, the recording apparatus 1 can reproduce a program based on the content data stored in the storage unit 12. Since the storage unit 12 composed of a non-volatile memory or a hard disk reads data faster than the optical disk 6, the program can be reproduced more smoothly than when the program is reproduced based on the content data recorded on the optical disk 6. It is possible to suppress stress applied to the user. In particular, in the case of the recording apparatus 1 that stores content data in the storage unit 12 together with the recording of the content data on the optical disc 6 when the program is broadcast, the content data of the program to be reproduced may be stored in the storage unit 12. Therefore, the program can be played smoothly at a high frequency.

  In the present embodiment, when the unformatted optical disk 6 is loaded, the recording apparatus 1 performs the process of registering the optical disk 6 after formatting the optical disk 6. Thereby, the optical disk 6 is registered only by mounting the unformatted optical disk 6 in the recording apparatus 1, and the user can create and use the registered optical disk 6 without troublesome work. In the present invention, the recording apparatus 1 can cancel the state in which the optical disk 6 is registered by deleting the media ID of the optical disk 6 stored in association with the storage area of the storage unit 12. As a result, when there is a shortage of storage areas not associated with the optical disk 6 in the storage area of the storage unit 12, the state in which the optical disk 6 is associated with the storage area is resolved, and a new optical disk is stored in the storage area. 6 can be associated. For example, when the optical disk 6 on which the content data is recorded is used for reproduction only, it is possible to cancel the registration of the reproduction-only optical disk 6 and register another optical disk 6 for recording.

  Furthermore, in the present embodiment, the recording apparatus 1 records reservation information on the optical disc 6, and when the optical disc 6 is loaded, the recording information stored therein and the reservation information recorded on the optical disc 6 are recorded. Synchronize. Thereby, even when the reservation information is recorded on the optical disc 6 by another recording device 1, the reservation information can be managed by the recording device 1 and the content data can be reliably recorded.

  Furthermore, in the present embodiment, when the optical disc 6 to be reserved for recording is not loaded and there is no free space in the corresponding area for storing the content data of the program reserved for recording. Since the optical disk 6 is configured to warn that the optical disk 6 should be mounted, the content data of the desired program can be reliably recorded on the optical disk 6 desired by the user, and the corresponding optical disk 6 is mounted.
